Classic Comic Strip of the Day
Little Nemo in Slumberland
Nemo dreams he is in a growing mushroom forest, and the panels themselves swell to make room for the mushrooms. (The Commons file page also carries a mismatched 26 July 1908 sentence; the filename, the recorded date, and the page itself are 22 October 1905.)
